Castor Oil.—The castor oil plant is really a native of India, but it is also cultivated in the United States (Illinois) and Egypt.
A typical commercial sample tested:—

Fish and Marine Animal Oils.—Various oils of this class have, until recently, entered largely into the composition of soft soaps, but a demand has now arisen for soft soaps made from vegetable oils.
We quote a few typical analyses of these oils:—
